Claims. 1

My invention relates to a conveyer means for transporting articles into,through and from a printing zone; more particularly, the aforesaidconveyer means comprises article-supporting chucks mounted on anintermittently movable disk and an endless conveyer movable step-bystepfor receiving printed articles from the re spective chucks.

In accordance with my invention, a printing impression is applied byrolling contact to an article having a wall surface capable of resistingthe thrust of the printing member without deformation.

Further in accordance with my invention, there is provided anintermittently movable disk with which is associated a plurality ofduplicate chucks of novel construction, each of these chucks serving asa means for conveying an article through the printing zone of a printingpress.

Further in accordance with my invention. a conveyer comprising an in.ermittently movable disk as referred to above is combined with anendless ccnveyer which receives the printed articles and transports themfrom the printing press.

Various other objects, advantages and tea tures of my invention willbecome apparent from the following detailed description.

My invention resides in the combined printing press and conveyer means,chuck construction, combined conveyers, features and arrangements of thecharacter hereinafter described and claimed.

For an understanding of my invention and for an illustration of one ofthe forms thereof, reference is to be had to the accompanying drawings,in which:

Referring to Fig. 1, P represents a suitable printing press which isherein shown as comprising a base I on which is journalled a blanketcylinder 2 carrying an arcuate rubber blanket 3. Disposed adjacent theblanket cylinder 2 and in driven relation with respect thereto is aplate cylinder 4 which carries a printing plate, not shown, to which inkis applied by any suitable inking arrangement, not shown.

A printing arrangement of the general character hereinbefore describedis illustrated in a detailed manner in U. 8. Letters Patent to A. J.Ford, No. 1.092,830. More specifically, the aforesaid printingarrangement is of the type under present commercial production by theRutherford Machinery Co. and known as a Tube printing machine.

I When the operating motor for the printing press P is energized, theblanket cylinder 2 is caused to rotate in a counter-clockwise direction,Fig. 1, at a desired constant speed. Responsive to the rotation of theblanket cylinder 2, the plate cylinder 4 rotates in a clockwisedirection, Fig. l, to thereby apply an impression of the printing plateto the rubber blanket 3 once for each rotative cycle of the blanketcylinder 2, these impressions always being applied to the same area ofsaid rubber blanket 3.

As shown in Figs. 1, 4 and 5, a shaft 5 is journalled in bearings 6upstanding from an extension Ia of the aforesaid base i. Under thecontrol of the known Geneva movement mechanism forming a part of theprinting press, steps of rotative movement are applied to the shaft 5,each step of rotative movement, in the form of the invention hereinshown, being through an angle of sixty degrees. Secured to one end ofthe shaft 5 is a disk which, with the form of the invention hereinshown, carries six chucks C of duplicate character as hereinafterdescribed.

Each of the chucks C comprises a plate 8 secured to the disk I by a pin9 and a screw 9a, or

equivalent, Fig. 7. The plate 8 supports a member H) which extends atright angles to the plane of the disk I. The member It! carries twopairs of split collars H, I! and i2, 12, each collar being held inadesired adjusted position on the member iii by a locking screw it. Eachof the aforesaid collars comprises a plane surface, the plane surfacesof the respective collars I l l I being located substantially atopposite sides or the member l3 and the plane surfaces of the respectivecollars I2, I2 being located in the same manner.

A screw I4 is threaded into the plane surface of each of the collars II,II and I2, I2, The screws I4 which are associated with the respectiveouter collars II and I2 secure bars I5 thereto, respectively, each barI5 being provided with a. slot through which the attaching screw I4extends and these slots preferably being elongated so that the pair ofbars I5 may be adjusted transversely with respect to the member I!)while they are maintained in parallel relation with each other, Fig. '7.Each of the bars I5, when positioned as shown in Fig. 8, carries a metalroller I6 at the upper end thereof.

The screws I 4 which are associated with the respective inner collars IIand I2 secure bars I! thereto, respectively, the bars I! beingadjustably mounted in the same manner as described above with respect tothe bars I5. The bars I I, when positioned as shown in Fig. 8, carry therespective metal rollers I8 at the upper ends thereof and said lastnamed end of each of the bars I5 has an article-supporting member I9secured thereto by screws 20.

As shown in Fig. 7, the member ID, between the chuck C and the plate 8,has secured thereto a split collar 2i which comprises a radial arm 22having a passage within which is clamped the shank of a bolt 23 having ahead 24.

The member I0, at the side of the chuck C opposite the arm 22, hassecured thereto a split collar 25 in which is clamped one end of an arm26 having a recess alined longitudinally with the aforesaid bolt 23.Disposed within this recess is an anti-friction structure 21, therotatable element of which has secured thereto a disk 28 utilizable ashereinafter described.

Referring particularly to Figs. 4 and 5, the base extension I a is shownas having a pair of members 29 secured thereto and projecting therefromin parallel relation, these members 29 being disposed closely adiacentthe periphery of the disk I, Fig. l. Carried by the upper member 29 area pair of curved tracks 30, the upper ends of the tracks 30 terminatingin the respective sleeves 3011 which are freely slidable on said uppermember 29, each sleeve 30a being maintained in a desired adjustedposition by a locking screw 30b. As shown in Fig. 1, the tracks 30extend downwardly and terminate just short of the blanket cylinder 2.

Supported by the lower member 29 are a pair of .curved tracks 3|carrying, approximately midway between the ends thereof, the respectivesleeves 3Ia which are freely slidable on said lower member 29, eachsleeve 3Ia being maintained in a desired adjusted position by a lockingscrew 3| b. The tracks 3! extend upwardly and terminate just short ofthe blanket cylinder 2. In addition, the tracks 3I extend downwardly andterminate in a discharge position as hereinafter described.

In accordance with my invention, articles of any suitable character mayreceive printed impressions. In general, such articles are containerssuch as cans or bottles having side wall structures which receive theprinting impressions and which are capable, inherently, of resisting thethrust of the printing member without becoming deformed. I have hereinillustrated a bottle B as the article which receives the printingimpression and. as the term bottle is used hereinafter in thisspecification and in the appended claims, it shall be understood thatthe same is generically descriptive of true bottles, cans, containers orthe like.

In operation, the disk 'I rotates by sixty-degree steps in a clockwisedirection, Fig. 1. As each chuck C remains stationary in a loadingposition L, Fig. 1, a bottle B is deposited by an operator on the fourmetal rollers I6 and I8 of that chuck C in the loading position. Eachchuck 0 comprises a pair of the supporting members I9 which serve toprevent accidental or unintended dislocation of the bottle B from therollers I6 and I8.

After a bottle B has been loaded onto a chuck C, the latter moves to anidle position I, Fig. 1, and then to the printing position P. Whilemoving between the positions I and P, the bottle B is opposite thetracks 39 which should have been so adjusted on the upper member 29 thatthe vertical surfaces 3&0 are opposite the respective ends of the bodyof the bottle B. Accordingly, as the bottle moves from the position Itoward the position P, the track surfaces 300 serve to prevent movementof the bottle from its chuck in case that action should tend to occur.

When the bottle B reaches the position P, it remains stationary in thatposition while the printing operation proceeds. While in the position Pand as shown in Fig. 4, the surface or element of the bottle which facesthe blanket cylinder 2 should be tangent with respect thereto and shouldextend parallel to the longitudinal axis of said blanket cylinder 2. Thebottle is caused to take this proper position in its chuck C byadjustment previously effected on the chuck bars I5 and II.

The bottle B herein illustrated is one which has a conical body and,therefore, as shown in Fig. 7, it is necessary to open the set of barsI5, I! at the left to somewhat greater extent than the opening definedby the set of bars IE, IT at the right. This is accomplished byretracting the locking screws I3 of the collars H and II, adjustingthese collars circumferentially, and longitudinally if necessary, of themember I0 to properly position said first named set of bars I5 and I I,and. then tightening said locking screws I3. Should adjustment berequired of the set of bars I5, II at the right, Fig. '7, that operationmay be effected in a manner similar to that described above. Further, ifnecessary or desirable, any or all of the screws I4 may be retractedwhereupon any or all of the bars I5 and I1 may be adjusted with respectto the supporting collars therefor. After this has been done, thepreviously retracted screws I4 should be tightened.

Assuming that the chuck bars have been properly adjusted in the generalmanner described above, the bottle B, when in the printing position P,is supported as shown in Figs. 4 and 8. The timing is such that, soonafter the bottle B takes this position, the printing blanket 3 of theblanket cylinder 2, which rotates constantly in a counterclockwisedirection, Fig. 1, engages the bottle and causes the same to rotate in aclockwise direction, Fig. 8. In so doing, the blanket 3 contacts withthe entire outer surface of the body of the bottle B to thereby applythe printing representation thereto.

As will be observed from Fig. 8, the rollers IS and H3, in effect, forma cradle by which the bottle is supported while pressure and rotativemovement is applied thereto by the blan ret 3. The glass wall structureof the bottle B is of such character that fracture or deformation doesnot occur as a result of the applied pressure from the blanket 3.

The bolt 23 and the disk 28 are positioned opposite the bottle bottomand top, respectively, so as to form stop surfaces preventing undesiredlongitudinal movement of the bottle while the printing operationproceeds. When the bottle is of conical shape as illustrated, thepressure of the printing blanket 3 causes the same to move from left toright, Fig. '7. In so doing, the neck of the bottle engages the freelyrotatable disk 28 which effectively prevents further longitudinalmovement of the bottle. With non-conical bottles, this action is not soimportant.

After the printing blanket 3 passes beyond the printing position, thechuck C containing the printed bottle is given two steps of movement bythe disk I, the first step ending in the idle position I1 and the secondstep ending in the discharge position D. While moving from the positionP to the position D, the bottle is retained in its chuck C by thevertical surfaces 3lc of the tracks 3! which are positioned in parallelrelation with respect to the tracks 30 when the latter are positioned asdescribed above.

It will be understood that the chucks C all have the same adjustmentsapplied thereto for a given lot of duplicate bottles B each of which isto receive a printed impression. The disk 1 moves step-by-step in aclockwise direction, Fig. l, and, after each chuck arrives at theposition L, a bottle is deposited therein. The loaded chuck then carriesthe bottle to the first idle position I, then to the printing positionP, then to the second idle position I1, and then to the dischargeposition D where the bottle is removed from the chuck. Thereafter, thelast named chuck moves to another idle position I2 and then returns tothe loading position L.

With the form'of the invention herein disclosed, each bottle, as it isremoved from its chuck at the discharge position D, is automaticallypassed onto a conveyer of a character hereinafter to be described.

As shown in Fig. 1, the base I supports a standard structure 33 and, inlongitudinal alinement therewith, a U-shaped' bracket 34 rests upon thefloor or other supporting surface. Suitably secured to the bracket 34are the parallel upstanding standards 35, Fig. 2. The standard structure33 and the standards 35 have secured .iereto in suitable manner achannel beam 35 extending generally in a horizontal direction.

Referring particularly to Figs. 1 and 5, the channel beam 36, at the endthereof toward the right, Fig. 1, is shown as supporting a U- shapedbracket 3'! having vertical arms which form bearings for a horizontalshaft 38 carrying a gear wheel 59 at one end thereof. The gear wheel 55meshes with a gear wheel 46, Fig. 4, which is carried by one end of ashaft 4| journalled in bearings formed in the aforesaid base extensionis. The shaft 41, at the end thereof opposite the gear wheel 45, carriesa sprocket wheel 42 which is disposed in the same vertical plane with asprocket wheel 43 carried by the hereinbefore described shaft 5. Anendless p et Chain 44 engaged by a tightener sprocket wheel 45, Fig.coacts with the sprocket Wheels 42 and 43.

A hereinbefore stated, the shaft is rotated in a step-by-step mannerunder the control of the printing press motor. The shaft 5, by thesprocket chain 44, rotates the shaft 4| insimilar fashion and, by thegear wheels 40 and 35, the

6 shaft 38 is rotated in step-by-step manner under the control of theshaft 4|.

As shown in Fig. 5, the shaft 38 carries a pair of sprocket wheels 4'5,45 each of which comprises a member which is slidable in a slot 38aextending longitudinally of the shaft 38 whereby said sprocket wheels46, 46 may be freely adjusted longitudinally of the shaft 35 in themanner hereinafter described.

Referring to Figs. 1, 2 and 4, the channel beam 35, at the end thereoftoward the left, Fig. 1, is shown as supporting a second U-shapedbracket 41 having a base 41a which, as hereinafter described, isadjustable longitudinally of the channel beam 35, said bracket 41 havingvertical arms which form bearings for a horizontal shaft 48. Carried bythe shaft 48 are a pair of sprocket wheels 49, 49 each of which, thesame as the aforesaid sprocket wheel 46 and 46, are splined to the shaft48 whereby said sprocket wheels 49, 49 may be freely adjustedlongitudinally of the shaft 48 in unison with the respective sprocketwheels 46, 46 as hereinafter described.

As shown particularly in Figs. 1, 4 and 6, the channel beam 35 supportsthird and fourth U- shaped brackets 56 and 5| which are disposedadjacent the respective brackets 31 and 41. Each of the brackets 56 and51 carries a horizontal rod 52, these rods 52 serving as supports onwhich parallel channel members 53, 53 are freely movable for adjustmenttransversely of the conveyer.

As illustrated in Fig. 4, each end of each of the channel members 53, 53carries a plate member 54 each of which terminates in a fork-shaped end54a freely receivable in a groove formed in the periphery of the hub ofthe adjacent sprocket wheel 46 or 49.

In accordance with the invention, the brackets 4'2, 55 and 56 have apair of parallel shafts 55, 55 journalled therein, these shafts beingdisposed outwardly of the respective channel members 53, 53. Each shaft55 has a pair of arms 55 secured thereto for oscillatory movementtherewith, these arms 55 being located closely adjacent the respectivebrackets 56 and 5!, Fig. 1. The upper end of each arm 56 is connected bya pair of links 51 with an ear 53a formed integrally with the adjacentchannel member 53. As shown in Figs. 1 and 4, each shaft 55 terminatesin a worm wheel 58.

Referring to Figs. 1, 2 and 4, the channel member 36 is shown as havinga plate 59 secured thereto, this plate 59, at opposite ends thereof,carrying the respective U-shaped brackets 66 in each of which isjournalled a shaft 5! having a hand wheel 62 secured to one end thereof,said shaft 5|, intermediate its ends, carrying a worm gear 63 whichmeshes with the adjacent worm wheel 58. The plate 59, as shown in Figs.1, 2 and 3, has two pairs of blocks 54 and 65 secured thereto by screws65, or equivalent. The blocks 64 extend above the upper level of theplate 59 and each block 54 carries a screw 51, the screws 61 beingthreaded, respectively, into passages provided therefor in the abovedescribed base 41a of the bracket 41.

The sprocket wheels 46, 46 and 49, 49 are longitudinally alined in pairsfor the reception of the endless sprocket chains 58 and 68,respectively. In order to prevent the upper spans of the chains 58, 66from sagging, bars 69, 59 are secured to the upper surfaces of therespective channel members 53, 53 by bolts 15. Similarly, to prevent thelower spans of the chains 68, 68

from sagging, supporting angle members H are secured to the lowersurfaces of the channel members 53 and 53, the angle members H carryingthe angle members 12 and 12, the lower horizontal surfaces of which areengaged by bottle-supporting members carried by the respective sprocketchains a hereinafter more particularly described. It will be understoodthat the bars 69, 69 together with the angle members 12, 12 extendsubstantially the entire distance between the pairs of sprocket wheels45, 45 and 49, 69.

In view of the foregoin description, it will be understood that theconveyer mechanism of my invention consists of two duplicate assemblies,each of which comprises a channel member 53, sprocket wheels 45 and 49,a sprocket chain 68 together with the sag-preventing supports for theupper and lower spans thereof. Further, these assemblies are freelymovable toward or from each other by reason of the fact, first, that thesprocket wheels 46 and 39 are freely movable longitudinally of therespective shafts 38 and 48 and, second, that the channel members 53, 53are freely movable on and with respect to their supporting rods 52.

In order to move one of the aforesaid assemblies with respect to theother assembly, the operator rotates that hand wheel 62 which isassociated with the assembly to be moved to thereby rotate theassociated shaft 55 by energy transmitted thereto through theintermeshed gear wheels 58 and 53. As a result, the arms 55 are movedeither clockwise or counter-clockwise, Fig. 6, depending upon thedirection of rotation of the hand wheel 62, to thereby move the channelmember 53 either toward or from the other channel member 53. Obviously,the other assembly may be adjusted either toward or from the first namedassembly by effecting movement of its hand wheel 62 in the properdirection. In this manner, the sprocket chains 68, 68 are positioned adesired distance from each other.

The sprocket chains 68, 68 may be tightened or loosened as desired byrotating the screws 6'1 in the proper direction, these screws coactingwith the bracket base 41a whereby the bracket 41 and the pair ofsprocket wheels carried thereby are moved either from or toward theother pair of sprocket wheels.

As indicated particularly in Fig. 9, each third link of each of thesprocket chains 68, 58 comprises an outwardly extending supportingmember E3 to which, by screws or the like 14, is secured a V-shapedmember having a tube 16 formed from rubber or the like on each legthereof. As indicated in Fig. 4, the members 15 on the two sprocketchains 68, 68 are alined in pairs transversely of the machine.

In accordance with the invention, the conveyer comprising the chains 68,68 is so positioned that the pairs of members 15 pass beneath thedischarge position D as the upper spans of the sprocket chains movestep-by-step from right to left, Fig. 1. Further, the timing is suchthat each transversely alined pair of the members 15 arrives at theposition D at the same time as a chuck C. As shown in Figs. 1 and 9, thetracks 3i terminate at the position D in such manner that a bottle 13drops from the chuck with which it has been associated and comes to restupon a pair .of the transversely alined members 15 as the latter come torest in said position D. In response to the next succeeding steps of thedisk 1 and the conveyer chains 68 and 68, the bottle B which has justbeen deposited on said last named members 15 moves one step on itsjourney from right to left, Figs. 1 and 9, and the next pair oftransversely alined members 15 move into the position D and receive abottle B from the following chuck on the disk 8. In this manner, thebottles which receive printing impressions in the printing zone areremoved individually from the chucks and deposited upon the conveyerchains 63 and 68, the latter serving to move the bottles from right toleft, Fig. 1, so that an operator may conveniently remove and dispose ofthem as desired.

It will be understood that the hereinbefore described assemblies each ofwhich comprises a channel member 53, sprocket wheels 46 and 49 and asprocket chain 68 are transversely adjustable so that the V-shapedmembers 15 will arrive at the position D in proper relation with respectto each other and with respect to a bottle B as it descends from itschuck so that said bottle will be properly supported for movement fromright to left, Fig. 1.

From a consideration of Fig. 6, it will be understood that the rubbertubes 16 associated with the V-shaped members 15 rest upon the anglemembers 12 to prevent sag of the lower spans of the sprocket chains 86,86 as such lower spans move from left to right, Fig. 1.

While the invention has been described with respect to a certainparticular preferred example which gives satisfactory results, it willbe understood by those skilled in the art after understanding theinvention, that various changes and modifications may be made withoutdeparting from the spirit and scope of the invention and it is intendedtherefore in the appended claims to cover all such changes andmodifications.
